Evaluating the effects of open/closed eyes and age-related differences on center of foot pressure sway during stepping at a set tempo

Trajectory length of pitch vs. roll: Technique for assessment of postural stability

“…In the mentioned study, certain instability was evident in women older than 50 years when a foam surface was introduced and in women older than 60 years when a firm surface was used. Similar conclusions are presented in Abrahámová and Hlavačka (2008), Aoki et al (2012). Thus, it can be concluded that in the case of subjects standing on a FiS, the identified difference between HS and Pts is caused by the degenerative cerebellar disorder.…”

“…It is generally known that the movement of the trunk (where the center of the mass of the whole body is located) and other body segments is directly related to the movement of the center of pressure which is traditionally used to study postural stability (Horak & Hlavacka, 2001;Tia, Saimpon, Paizis, Mourey, Fadiga, & Pozzo, 2011). Aoki et al (2012) found that there were insignificant differences in 10-60 year old subjects in CoP sway parameters: circumference, rectangular area, left-right width, and front-back width in both the cases (eyes open/closed), i.e. no significant age-related differences were found in any of the CoP sway parameters (i.e.…”

“…A comparison of exclusively age groups would not be definite. The parameters of the body sway in healthy participants within the age span between 20 and 60 years vary only slightly, as studies have shown (Abrahámová & Hlavačka, 2008;Aoki et al, 2012). It is generally known that the movement of the trunk (where the center of the mass of the whole body is located) and other body segments is directly related to the movement of the center of pressure which is traditionally used to study postural stability (Horak & Hlavacka, 2001;Tia, Saimpon, Paizis, Mourey, Fadiga, & Pozzo, 2011).…”

Laterality of Static and Dynamic Balance Abilities during One-leg Standing

“…Data sampling frequency was 20 Hz. In a previous study [1], persons with larger total trace length and change velocity of COP were evaluated as "inferior" in postural control ability. Hence, participants with smaller total trace length in this study were judged "superior" in postural stability.…”

“…Static balance ability is exerted to maintain a stable stationary posture, and dynamic balance ability is exerted to maintain stable posture during active movements such as walking, running, or recovering a posture [1]. Humans need greater balance ability exertion during one-leg standing than during both-legs standing to maintain stable posture because of a small supporting base area and an imposing large load on one leg.…”
